The Lowdown
Hey crew, it's Rusty. Let's talk surf.
We've got a big, fat pause button pressed on the waves for the foreseeable future. The first part of this outlook is a ghost town for surf. From Friday the 11th all the way through to late September, it's flat, small, and messy. Not worth getting wet. The water is sitting at 18° , a touch warmer than usual, but you won't feel it on dry land.
After what feels like an eternity, we finally get a pulse. The day to circle on your calendar is Friday the 25th of September. That's the standout.
The morning of the 25th brings a 7ft swell from the East, with a 8-second period. The wind is moderate and offshore, making for clean faces. The combined energy is pumping hard (555). This is expert-level juice, no doubt. The afternoon drops a bit to 5ft from the East, with a 9-second period, and it stays clean with a moderate offshore breeze. Energy is still strong (404). That heavy rain in the afternoon will be a pain, but for waves that size, it’s worth it.
Thursday the 24th of September is the only other day with any size. The afternoon brings a 7ft swell from the ENE, but with a short 7-second period. It's going to be a choppy, wind-blown mess with the cross-onshore winds. The energy is massive (518), which tells me this is more of a kite-surfing day than a paddle surf day.
So, the plan is simple: wait it out, and be ready for the morning of the 25th.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
